Hydro-micromechanical modeling of wave propagation in saturated granular media
Hongyang Cheng, Stefan Luding, Nicolás Rivas +2
Biot's theory predicts the wave velocities of a saturated poroelastic granular medium from the elastic properties, density and geometry of its dry solid matrix and the pore fluid,…
Solvation effects and contact angle saturation in electrowetting
Nicolas Rivas, Jens Harting
Electrowetting of nanodrops is studied for aqueous electrolyte mixtures. We report a new method for controlling the degree of deformation and minimum attainable contact angle by va…
From creeping to inertial flow in porous media: a lattice Boltzmann - Finite Element study
Ariel Narváez, Kazem Yazdchi, Stefan Luding +1
The lattice Boltzmann method has been successfully applied for the simulation of flow through porous media in the creeping regime. Its technical properties, namely discretization,…
Quantification of the performance of chaotic micromixers on the basis of finite time Lyapunov exponents
Aniruddha Sarkar, Ariel Narváez, Jens Harting
Chaotic micromixers such as the staggered herringbone mixer developed by Stroock et al. allow efficient mixing of fluids even at low Reynolds number by repeated stretching and fold…
Evaluation of pressure boundary conditions for permeability calculations using the lattice-Boltzmann method
Ariel Narváez, Jens Harting
Lattice-Boltzmann (LB) simulations are a common tool to numerically estimate the permeability of porous media. For valuable results, the porous structure has to be well resolved re…
Quantitative analysis of numerical estimates for the permeability of porous media from lattice-Boltzmann simulations
Ariel Narváez, Thomas Zauner, Frank Raischel +2
During the last decade, lattice-Boltzmann (LB) simulations have been improved to become an efficient tool for determining the permeability of porous media samples. However, well kn…
